When do I need to upload photos?

For Tier 1, 2 and 3 jobs, photos at completion are encouraged but not required. For Tier 4 jobs (£15k–£50k), photo evidence is required at each of the three milestones. Take the photos at the job site as you complete each stage, and keep the originals — they are your record that the stage was done, and they are reviewed as part of that milestone. If the work at a milestone is later questioned, your photos are the evidence the review considers.
